通过脉冲激光沉积技术成功生长了单相、c 轴取向的 Y 型磁铅石（Ba2Co2Fe12O22；Co2Y）薄膜，其 c 轴长度非常大，为 43.5 Å。关键点是高温沉积和在薄膜和MgAl2O4(111)基底之间插入CoO缓冲层。从透射电子显微镜 (TEM) 分析来看，CoO 缓冲层被消耗以形成 Co2Y 和基底的原子级清晰界面。利用超导量子干涉装置磁力计验证了外延薄膜的高磁性能。
Single phase, c-axis oriented thin films of Y-type magnetoplumbite (Ba2Co2Fe12O22; Co2Y) with a very large c-axis length as 43.5 Å were grown successfully by pulsed laser deposition technique. The key points were high temperature deposition and the use of CoO buffer layer inserted between the film and MgAl2O4(111) substrate. From the transmission electron microscope (TEM) analysis, the CoO buffer layer was consumed to make an atomically sharp interface of Co2Y and substrate. Superconducting quantum interference device magnetometer was used to verify the high magnetic properties of the epitaxial thin films.
